3. Problem 4.56 from the book

4.56. Absorption of acetone (A) from air by water.

Vapor-liquid equilibrium data in mole fractions for the system

acetone-air-water at 1 atm (101.3 kPa) are as follows:

y, acetone in air: 0.004 0.008 0.014 0.017 0.019 0.020

x, acetone in water: 0.002 0.004 0.006 0.008 0.010 0.012

(a) Plot the data as (1) moles acetone per mole air versus moles

acetone per mole water, (2) partial pressure of acetone versus g ace-

tone per g water, and (3) y versus x. (b) If 20 moles of gas contain-

ing 0.015 mole-fraction acetone is contacted with 15 moles of water,

what are the stream compositions? Solve graphically. Neglect water/

air partitioning.
